Direct bolt-on turbo (ko4 replacement)

BNR has reworked them with newer, lighter wheels for better spool. I'm not sure if there was also a flow improvement associated with going to the newer wheels. I'm also not sure if the housing has been changed or not. I heard a rumor it might have gone to a ball bearing setup, but I haven't been able to verify that yet.
is there any way to swap turbos>? give them old version and get the new version for a small fee?

Lol I was just at bnr with Bryan. We were talking about some other stuff going on with my shop. But the 2871 new revision is worth it. We installed it on team ss car and flow is the same but it holds boost a we but better till 7500 rpm. And the iat2s were a little lower

I just got my car tuned yesterday with my bnr 2871, but unfortunely one of my brand new in package 3 bar map was defective. So I had to get partially tuned on the stock sensors. Now I have to order new sensor. Anyway my tuner told me based on some of the pulls that the turbo would make about 360hp 410 tq.

I'll be using stock sensors on mine(they read up to 2.7bar) and I know that I'll be well in the over the 400whp mark.

Stop your crazy talk :P You can make 360 whp on the stock turbo! It'll last pull after pull after pull too.
There are way too many idiots that think 360 hp on the stock turbo is anything like 360 on a bigger turbo. Likewise too many people on this forum do not understand that bigger turbos mean the torque curve will come on later which means you will never get peak toque numbers like a tiny turbo.

of course the power in an aftermarket turbo is different than the stock turbo, but i just dont see the point in getting it if you arent gonna really utilize it....
and as far as powerband, i believe it has a lot to do with how its tuned, since my car pulls from 3500-5800 @24psi, then only dies to 22.5psi from 5800-6200 redline...just sayin
i really wanna see some numbers/graphs on here...lets see umm

Having 360whp on a ko4 vs say one on a bnr2871 is obviously better with the bnr. Doesn't fall on its face, so therefore power is linear. Looses a little tq. But not much. 360whp on the bnr isn't much but it's not bad. Talking with Bryan I asked what's the flow for the new revision and what I the out put it can safely without going out of the efficiency? He stated 24-26 is within its efficiency anything over its out of its efficiency. But he stated if you go more you can obtain more power which I know but he said 450chp is capabilities with going out of efficiency. So about 420-430 is basic capabilities to the wheel.
People have made more which I have one guy who made 432 whp which was on e47 but it was pushing limits.

i was just sayin that for $2-2500, i better have a much faster car, and if not, then why spend the money....
i really dont wanna go over 25psi on any turbo i get, really just wanna stay at the 24psi i am at now currently on the stock turbo, and want 400whp/400wtq on 93 gas...

I just talked to the local rep for Borg Warner and they are making some changes to the EFR series and dont expect to have any ready untill after the first of 2013
Hope somebody else comes up with something bolt on soon. Looking for at least 475 HP

I'm happy I got one, but I hope those revisions aren't worth it!

i am wondering the same thing...
What turbo makes the most power at 20-23psi on pump gas?

I think a GT3076 would most likely be one answer. The S252 might be in that realm too. I dunno for sure.
